Origin
Meaning and history of Kylain
The name Kylain has its origins in ancient Celtic languages and cultures. It is derived from the Old Irish word "cailín" which means "young woman" or "girl". This name was commonly used in Ireland, Scotland, and parts of Wales during the Middle Ages.
One of the earliest recorded uses of the name Kylain can be found in the Annals of Inisfallen, an Irish chronicle dating back to the 12th century. It mentions a woman named Kylain who was a noble and landowner in County Kerry, Ireland.
In the 14th century, there is a record of a Kylain MacCormick who was a renowned poet and bard in the Scottish Highlands. Her works, though mostly lost, were celebrated for their lyrical beauty and storytelling.
During the Renaissance period, a Kylain O'Malley was a famous Irish pirate queen who terrorized the seas around the British Isles in the late 16th century. She was known for her fearlessness and leadership skills.
In the 17th century, Kylain Ní Dhomhnaill was an influential Irish noblewoman and patron of the arts. She commissioned numerous works of literature and poetry, helping to preserve the Irish language and culture.
In more recent history, Kylain McAlister (1892-1976) was a renowned Scottish novelist and playwright. Her works often explored themes of identity, tradition, and the struggle between modernity and cultural heritage.

FAQ
Kylain: questions and answers
How many people in the U.S. are named Kylain?
Name Census puts the figure at roughly 11 living Americans. We arrive at this by taking every SSA birth registration for Kylain going back to 1880 and adjusting each cohort for expected survival using CDC actuarial life tables. The result is an age-weighted living-bearer count, not a raw birth total. That works out to about 1 in 31,159,485 US residents.
Is Kylain a common name?
We classify Kylain as "Very Rare". It ranks above 30.8% of all first names in the SSA dataset by living bearers. Across the full history of the data, 11 babies have been registered with this name.
When was Kylain most popular?
The single biggest year for Kylain was 2024, when 6 babies received the name. The fact that the average living Kylain is about 3 years old gives you a rough sense of which era contributed the most bearers who are still alive today.
What does the SSA popularity chart show?
The chart tracks births, not the number of people alive with the name today. Each point shows how many babies were given the name Kylain in that year. That makes it useful for spotting when the name rose, peaked, or faded.
Is Kylain a male name?
Yes, 100.0% of people registered as Kylain in the SSA data are male. You can see the full per-sex comparison in the gender distribution section above, which includes the latest year rank, birth count, and peak year for each sex.
Is Kylain still being used today?
Yes. The SSA still recorded Kylain in 2024, and the page above shows its latest-year rank where available. A name can be well past its peak and still remain in steady use, especially if it built up a large population over earlier decades.
Why can a name have a lot of living bearers even if it is not trendy now?
Because living-bearer counts and current baby-name popularity measure different things. A name like Kylain can build up a very large population over many decades, even if fewer parents are choosing it now than they did at its peak.
Where does this data come from?
First-name figures come from the Social Security Administration's national baby name files, which cover every name on a birth certificate from 1880 to 2024. Living-bearer estimates layer in CDC actuarial life tables broken out by sex to account for mortality. The population baseline (342,754,338) is the Census Bureau's latest national estimate. You can read the full calculation on our methodology page.
Does every first name have Census demographic data?
No. The public Census first-name release only covers names that met the Bureau's publication rules, so many rarer names in the SSA files do not have a published Census demographic snapshot. In those cases, the page still shows the SSA trend, gender history, and state data.
